The motivation for this article is to disperse one of the myths around cloud that sometimes I hear. Usually, this myth is given by the following sentence: ... Benefits of Cloud is that you deploy an application on multiple computers automatically as soon as you increase the number of users. The phrase cloud solutions XYZ, you automatically keeps an eye on this situation, bakery display trays take care to provide a new computing power and dynamic load balancing. No matter what level of technology on language or platform you use, it is naive enough to think that you ensure that cloud right for your application.
Imagine zmrzlinářku that the swimming bakery display trays pool turns into an ice cream cone. Because at its stand form long queues and people are unhappy, think of a clever, the need to buy another machine for ice cream. Question for five crowns is: will help other ice cream machine to shorten the queue? . If we think in terms of the series X-Files, which means that zmrzlinářka bakery display trays is a hybrid of human and octopus hands and do not have spines, then give us the new machine for ice cream does not help. Why not think that will help us to add new "Ice-cream makers" in the cloud, if it is not our "zmrzlinářka" ready? In addition, adding one more "Ice-cream makers" might get rid of one problem, but again we will be added to a completely different family problems, which we previously did not know or we could boldly ignored. Just imagine the comic situation, as we tentacles alias hands of our zmrzlinářky bakery display trays / squid fighting with cones on a tray or jelly, bakery display trays of which return money back.
I saw correct I read a couple of applications that can scale in a way that many developers considered as a showcase for the cloud. If they look under the hood of the imaginary, you will find that it is necessary to fulfill the total number of non-trivial conditions to be able to make the possibility of the cloud while maintaining reasonable economic and operating conditions.
Architecture must deploying applications in the cloud count from design to implementation with maintaining favorable price / performance ratio with maintaining high manageability applications. Failure of any of these terms, you are missing one, I repeat one of the benefits of the cloud. Architecture and Implementation of a compromise
Architecture applications using the cloud is the possibility of compromise, often by bloody compromises that you have to be willing to pay. The first compromise bakery display trays is bezstavovosti rate versus the complexity of the programming model. Fully stateless application never has, because it would be inefficient in terms of the amount of data transmitted and robust abstraction, which would have been over the need to build. Another compromise is the local availability of data compared to their timeliness. From the performance point of view it would be best if the data is always available locally bakery display trays and the best in memory. If those dates can operate multiple independent processes, you have to choose between their availability and consistency aka CAP theorem.
The technology we use, may not work well in the cloud. Therefore clodových solution providers offer proprietary technologies that are tuned to operate in the cloud. The compromise, which will set when you use them is called vendor lockin, thus depending on the supplier. Economical Scalability bakery display trays
Many problems that we can solve the architectural level and its implementation using a compromise could be reflected in the efficiency with which we will be able to use the acquired resources in the cloud. In other words, you have an application architecture that will scale for a lot of money. It's not only the scale, but to be able to scale efficiently in terms of costs. When a new user for one month get one crown and calculate that cost just for the rental of hardware, the crown and ten cents, to be able to serve those users, then your application scales, although technically, but not economically. Architecture and its implementation should use the maximum sharing of resources in maintaining bakery display trays acceptable level of interference. Operovatelnost bakery display trays
After the sin of one of the conditions is often neglected manageability applications. If you are not talking about the obvious, such as monitoring, then you need a tool which will configure the entire solution. Things start to really complicate, if your application is not a monolith, but it'll be split into more components deployed separately. If you look at the open source technology bakery display trays that Netflix released or Twitter, it is immediately apparent that around one core technology, they have a few others that allow her to run and manage. Mostly bakery display trays it is a technology for monitoring, dynamic management and service discovery. It is important to add that some cloud providers offer similar tools. Not samospasitelných solutions
Yes, the cloud offers interesting possibilities, but only if your application with them counts. I would not want this article sounded against the cloud, or vice versa. The whole note is that we should learn to write applications in a way that we u
